The choice of bluetooth headset

When purchasing a Bluetooth headset, mainly consider the following aspects:

Quality of products

Buying a Bluetooth headset should pay more attention to the quality and performance of the product, such as battery life, radiation level, etc. Generally, inferior or inferior Bluetooth headsets cannot be guaranteed in terms of workmanship or materials due to cost control. The product quality is poor, the actual use function data is very different, and the radiation dose is very high.

conversation quality

Because call quality is a basic parameter to measure the quality of a Bluetooth headset, in general, using a Bluetooth headset with a pole-type design, because the microphone is closer to the mouth, the call quality obtained is relatively better than other types of products.

Standby time

Because this is the same as the daily use of mobile phones, the longer the standby time of the headset, the less troublesome charging can be avoided, which is also one of the standards for measuring the performance of Bluetooth headsets.

Wearing comfort

Human ears are relatively delicate. If the ear-hook material of the earphone is not good, or there are some defects in the design, it will cause discomfort after wearing it for a long time. Therefore, you should check carefully before purchasing and choose a Bluetooth headset that suits your ear shape.

Purpose

Just choose a headset with a lower price, preferably the earmuff type with volume adjustment, ② for listening to the news.

Compatibility

When buying a Bluetooth headset, the most important question is whether the phone is compatible with the headset. Some bluetooth earphones are not compatible with mobile phones, mainly because of different specifications. There are three main specifications of Bluetooth headsets – HandfreeProfile (HFP), HeadsetPro-file (HSP) and A2DP. HFP stands for Hands-Free Function while HSP stands for Headset Function. Consumers must first figure out which specifications their mobile phone supports, and then choose the right Bluetooth headset to pair with. A2DP refers to the Advanced Audio Distribution Profile, which allows the transmission of stereo audio signals with much better quality than HFP and HSP.

The Bluetooth headset in HFP format supports relatively complete functions of mobile phones. Consumers can operate hands-free options such as redial, call hold, and call rejection set by mobile phones on the headset. Almost all Bluetooth headsets launched by Nokia, Motorola, Sony Ericsson, etc. support the HFP format. There are also some models that support both HFP and HSP. For example, the Pymet Bluetooth headset is in A2DP format, compatible with HFP and HSP formats, and is the best format version at present.

Chip brand

There are three major chip suppliers of Bluetooth headsets, one is CSR in the United Kingdom, and the other is Broadcom in the United States. Broadcom’s products account for more than 80% of the market.

Transmission distance

The transmission distance of Bluetooth headsets is also a problem that everyone is more concerned about. The transmission distance of the Bluetooth headset has nothing to do with the Bluetooth version, but mainly depends on the advanced level of technology. The standard transmission distance of PowerClass2 is 10 meters; while the upgraded PowerClass1 increases the transmission distance to 100 meters and provides Hi-Fi stereo effects. Generally speaking, the distance between the mobile phone and the Bluetooth headset is not too far, and the safe transmission distance is about 2 meters to 3 meters.

Version

When consumers purchase Bluetooth headsets, they often see numbers such as Bluetooth 1.1, 1.2, 2.0+EDR, 2.1+EDR, and the numbers represent different specifications. At present, 1.1 is the most common, 1.2 is the new mainstream, 2.0 was launched in 2006, 2.1+EDR version, the latest is 3.0 is the mainstream, and 4.0 is the latest Bluetooth headset technology. These numbers represent the different versions, but also represent the headset. Anti-interference bluetooth headset capability. Different versions of Bluetooth are related to the quality of the received signal. The new version puts more emphasis on overcoming noise interference. All new versions are backward compatible, and consumers should measure price and demand when purchasing.
